Description

本考案は、鉄道車両の屋根上で架線に摺接する摺り板と、摺り板が固定される舟体とを備える集電舟に関する。 The present invention relates to a current collector boat comprising a sliding plate that is in sliding contact with an overhead line on the roof of a railway vehicle, and a boat body to which the sliding plate is fixed.

この種の集電舟において、舟体は、一般的に、鉄道車両の車長方向両端で下方に屈曲する垂下板部を有している。このものでは、降雪時に鉄道車両が走行すると、走行風により舟体の垂下板部に雪が付着しやすく、また、舟体の上面に積もった雪が一旦溶け垂下板部で再び凍ってしまいやすい。ここで、集電舟は、ばね等によりパンタグラフを介して押し上げられて、摺り板が架線に摺接するようにしている。そして、舟体に着雪した場合、雪の重みに比し集電舟の押し上げ力が不足して、架線との間で離線アークが発生してしまう。そのため、着雪しやすい舟体の垂下板部の面積を小さくして、垂下板部への着雪量を少量に抑えることが望まれる。 In this type of current collector boat, the boat body generally has a hanging plate portion that is bent downward at both ends in the vehicle length direction of the railway vehicle. In this case, when the railway vehicle travels during snowfall, snow tends to adhere to the hanging plate portion of the boat body due to the traveling wind, and the snow accumulated on the upper surface of the boat body once melts and freezes again at the hanging plate portion. Here, the current collecting boat is pushed up via a pantograph by a spring or the like so that the sliding plate is in sliding contact with the overhead wire. And when it snows on a hull, the raising force of a current collecting boat is insufficient compared with the weight of snow, and a separating arc will generate | occur | produce between overhead lines. For this reason, it is desirable to reduce the area of the drooping plate portion of the boat body that is likely to snow, and to minimize the amount of snow on the drooping plate portion.

そこで、従来、例えば特許文献１記載のものが知られている。このものでは、舟体の垂下板部の下端部を鉄道車両の車長方向内方に屈曲させ、その内端部を更に上方に屈曲させてその端部を舟体の下面に突き当て、舟体下面に閉断面部を形成している。これによれば、摺り板が架線に摺接するときに舟体が撓まないように剛性を確保しつつ垂下板部の高さ寸法を短くして、垂下板部の面積を小さくすることができる。 Thus, conventionally, for example, the one described in Patent Document 1 is known. In this case, the lower end portion of the hanging plate portion of the boat body is bent inward in the vehicle length direction of the railway vehicle, the inner end portion thereof is further bent upward, and the end portion is abutted against the lower surface of the boat body. A closed cross section is formed on the lower surface of the body. According to this, the height dimension of the drooping plate portion can be shortened and the area of the drooping plate portion can be reduced while ensuring rigidity so that the boat body does not bend when the sliding plate is in sliding contact with the overhead wire. .

然し、このものでは、舟体に閉断面部を形成することで構造が複雑になるため、加工コストが高く、また、閉断面部を通しての摺り板の固定作業が必要となって、その作業に手間がかかってしまう。 However, in this case, the structure becomes complicated by forming the closed cross section in the hull, so the processing cost is high, and it is necessary to fix the sliding plate through the closed cross section. It takes time and effort.

本考案は、以上の点に鑑み、舟体の垂下板部の高さを短くして、且つ、剛性を確保することを、舟体の加工コストアップや摺り板の固定作業性の悪化を招くことなく実現できるようにした集電舟を提供することをその課題としている。 In view of the above, the present invention shortens the height of the hanging plate portion of the hull and secures rigidity, thereby increasing the processing cost of the hull and deteriorating the workability of fixing the sliding plate. The challenge is to provide a collector boat that can be realized without any problems.

上記課題を解決するために、本考案は、鉄道車両の屋根上で架線に摺接する摺り板と、摺り板が固定される舟体とを備える集電舟であって、舟体は、鉄道車両の車長方向両端で下方に屈曲する垂下板部を有するものにおいて、垂下板部に、垂下板部の剛性を高める補強板を取り付けることを特徴とする。 In order to solve the above-mentioned problem, the present invention is a current collector boat comprising a sliding plate that is in sliding contact with an overhead line on a roof of a railway vehicle, and a boat body to which the sliding plate is fixed. In the one having the hanging plate portion bent downward at both ends in the vehicle length direction, a reinforcing plate for increasing the rigidity of the hanging plate portion is attached to the hanging plate portion.

本考案によれば、舟体の垂下板部の高さ寸法を短くしても、補強板により垂下板部の剛性を確保できる。従って、剛性を確保しつつ垂下板部の高さ寸法を短くして、垂下板部の面積を小さくし、垂下板部への着雪量を少量に抑えることができる。また、舟体の垂下板部に補強板を取り付けるだけであるため、舟体が簡素な構造となり、舟体の加工コストアップを招かない。更に、舟体下面に閉断面部を設けるものと異なり、舟体下面に摺り板を固定するための作業スペースを広く確保することができ、摺り板の固定作業性の悪化を招くこともない。 According to the present invention, even if the height dimension of the drooping plate portion of the boat body is shortened, the rigidity of the drooping plate portion can be secured by the reinforcing plate. Therefore, the height dimension of the hanging plate portion can be shortened while securing rigidity, the area of the hanging plate portion can be reduced, and the amount of snow on the hanging plate portion can be suppressed to a small amount. Moreover, since the reinforcing plate is simply attached to the hanging plate portion of the hull, the hull has a simple structure and does not increase the processing cost of the hull. Further, unlike the case where the closed cross section is provided on the lower surface of the hull, a wide working space for fixing the sliding plate to the lower surface of the hull can be secured, and the fixing workability of the sliding plate is not deteriorated.

図１及び図２を参照して、１は、鉄道車両用パンタグラフが具備する本考案の実施形態の集電舟を示している。図３も参照して、集電舟１は、鉄道車両の屋根上で架線に摺接する複数枚の摺り板２と、摺り板２の両側に配置される複数枚の補助摺り板３と、摺り板２及び補助摺り板３が固定される舟体４とを備えている。尚、摺り板２には、下方にのびるボルト２１が固定されており、このボルト２１を舟体４に貫通させた状態で、ボルト２１に下方からナット２２を締め込むことにより舟体４に摺り板２が固定される。 1 and 2, reference numeral 1 denotes a current collecting boat according to an embodiment of the present invention, which is provided in a railcar pantograph. Referring also to FIG. 3, the current collector boat 1 includes a plurality of sliding plates 2 that are in sliding contact with the overhead line on the roof of the railway vehicle, a plurality of auxiliary sliding plates 3 that are disposed on both sides of the sliding plate 2, and a sliding plate. And a boat body 4 to which the plate 2 and the auxiliary sliding plate 3 are fixed. Note that a bolt 21 extending downward is fixed to the sliding plate 2, and the bolt 21 is passed through the boat body 4, and then the nut 22 is tightened onto the bolt 21 from below to slide onto the boat body 4. The plate 2 is fixed.

舟体４は、鉄道車両の車長方向両端で下方に屈曲する垂下板部４１を有している。垂下板部４１には、鉄道車両の車長方向外側を向く面に、垂下板部４１の剛性を高める補強板４２がスポット溶接によりに取り付けられている。 The hull 4 has a hanging plate portion 41 that is bent downward at both ends in the vehicle length direction of the railway vehicle. A reinforcing plate 42 that increases the rigidity of the drooping plate 41 is attached to the drooping plate 41 on the surface facing the vehicle length direction outside of the railway vehicle by spot welding.

ところで、降雪時に鉄道車両が走行すると、走行風により舟体４の垂下板部４１に雪が付着しやすく、また、舟体４の上面に積もった雪が一旦溶け垂下板部４１で再び凍ってしまいやすい。そして、集電舟１は、ばね等によりパンタグラフを介して押し上げられるが、舟体４に着雪した場合、雪の重みに比し集電舟１の押し上げ力が不足して、架線との間で離線アークが発生してしまう。そのため、着雪しやすい舟体４の垂下板部４１の面積を小さくして、垂下板部４１への着雪量を少量に抑えることが望まれる。 By the way, when a railway vehicle travels during snowfall, it is easy for snow to adhere to the drooping plate portion 41 of the hull 4 due to the traveling wind, and the snow that has accumulated on the upper surface of the hull 4 once melts and freezes again in the drooping plate portion 41. . The current collecting boat 1 is pushed up via a pantograph by a spring or the like. However, when snow falls on the hull 4, the raising force of the current collecting boat 1 is insufficient compared to the weight of the snow, so In this case, an arc of separation occurs. Therefore, it is desired to reduce the area of the drooping plate portion 41 of the boat body 4 that is likely to snow, and to suppress the amount of snow on the drooping plate portion 41 to a small amount.

ここで、本実施形態では、垂下板部４１に、上記の如く垂下板部４１の剛性を高める補強板４２を取り付けるため、舟体４の垂下板部４１の高さ寸法を短くしても、補強板４２により垂下板部４１の剛性を確保できる。従って、剛性を確保しつつ垂下板部４１の高さ寸法を短くして、垂下板部４１の面積を小さくし、垂下板部４１への着雪量を少量に抑えることができる。また、舟体４の垂下板部４１に補強板４２を取り付けるだけであるため、舟体４が簡素な構造となり、舟体４の加工コストアップを招かない。更に、舟体４の下面に上記従来例の如く閉断面部を設けるものと異なり、舟体４の下面に摺り板２を固定するための作業スペース（ナット２２を締め込むためのスペース）を広く確保することができ、摺り板２の固定作業性の悪化を招くこともない。 Here, in this embodiment, in order to attach the reinforcing plate 42 that increases the rigidity of the hanging plate portion 41 to the hanging plate portion 41 as described above, even if the height dimension of the hanging plate portion 41 of the boat body 4 is shortened, The reinforcing plate 42 can ensure the rigidity of the hanging plate portion 41. Therefore, the height dimension of the hanging plate portion 41 can be shortened while securing rigidity, the area of the hanging plate portion 41 can be reduced, and the amount of snow on the hanging plate portion 41 can be suppressed to a small amount. Further, since the reinforcing plate 42 is simply attached to the hanging plate portion 41 of the hull 4, the hull 4 has a simple structure, and the processing cost of the hull 4 is not increased. Further, unlike the conventional example in which the closed section is provided on the lower surface of the hull 4, the work space (the space for tightening the nut 22) for fixing the sliding plate 2 to the lower surface of the hull 4 is widened. It can be ensured, and the fixing workability of the sliding plate 2 is not deteriorated.

以上、本考案の実施形態について図面を参照して説明したが、本考案はこれに限定されない。例えば、上記実施形態では、垂下板部４１にスポット溶接により補強板４２を取り付けているが、ボルトや接着剤を用いて取り付けてもよい。また、上記実施形態では、垂下板部４１の補強板４２の取り付け面を鉄道車両の車長方向外側を向く面としているが、車長方向内側を向く面としてもよい。 As mentioned above, although embodiment of this invention was described with reference to drawings, this invention is not limited to this. For example, in the said embodiment, although the reinforcement board 42 is attached to the drooping board part 41 by spot welding, you may attach using a volt | bolt or an adhesive agent. Moreover, in the said embodiment, although the attachment surface of the reinforcement board 42 of the drooping board part 41 is made into the surface which faces the vehicle length direction outer side of a railway vehicle, it is good also as a surface which faces the vehicle length direction inner side.
